Mass measurements towards doubly magic Ni-78 : Hydrodynamics versus nuclear mass contribution in core-collapse supernovae
2022
International audience; We report the first high-precision mass measurements of the neutron-rich nuclei 74,75Ni and the clearly identified ground state of 76Cu, along with a more precise mass-excess value of 78Cu, performed with the double Penning trap JYFLTRAP at the Ion Guide Isotope Separator On-Line (IGISOL) facility. These new results lead to a quantitative estimation of the quenching for the N=50 neutron shell gap. The impact of this shell quenching on core-collapse supernova dynamics is specifically tested using a dedicated statistical equilibrium approach that allows a variation of the mass model independent of the other microphysical inputs. We conclude that the impact of nuclear m…

NEMESIS Setup for Indirect Detection of WIMPs
2022
We summarize the evidence for DM-like anomalies in neutron multiplicity spectra collected underground with Pb targets by three independent experiments: NEMESIS (at 210 m.w.e.) NMDS (at 583 m.w.e.), and ZEPLIN-II (at 2850 m.w.e.). A new analysis shows small but persistent anomalies at high neutron multiplicities. Adjusted for differences in detection efficiencies, the positions of the anomalies are consistent between the three systems. Also, the intensities match when corrected for the acquisition time and estimated detection efficiency. While the three measurements are inconclusive when analyzed separately, together, they exclude a statistical fluke to better than one in a million. To prove…

Technology Impact on Neutron-Induced Effects in SDRAMs : A Comparative Study
2021
International audience; This study analyses the response of synchronous dynamic random access memories to neutron irradiation. Three different generations of the same device with different node sizes (63, 72, and 110 nm) were characterized under an atmospheric-like neutron spectrum at the ChipIr beamline in the Rutherford Appleton Laboratories, UK. The memories were tested with a reduced refresh rate to expose more single-event upsets and under similar conditions provided by a board specifically developed for this type of study in test facilities. The board has also been designed to be used as a nanosatellite payload in order to perform similar tests. The neutron-induced failures were studi…
Plasmon mass scale in two dimensional classical nonequilibrium gauge theory
2018
We study the plasmon mass scale in weakly coupled strongly interacting nonabelian gauge theory in a two dimensional configuration that mimics the boost invariant initial color fields in a heavy ion collision. We numerically measure the plasmon mass scale using three different methods: a Hard Thermal Loop (HTL) expression involving the quasiparticle spectrum constructed from Coulomb gauge field correlators, an effective dispersion relation and the measurement of oscillations between electric and magnetic energies after introducing a spatially uniform perturbation to the electric field. We find that the hard thermal loop expression and the uniform electric field measurement are in rough agree…
Música [religiosa] moderna en Corea del Norte / Modern North Korean [Religious] Music
2017
Music is a field where North Korea has been for decades engaging in consistent though not extensive international exchanges. Music is there a major national art form, on which a considerable amount of national resourcesis devoted, and the quality of musical education is high. Its practical uses are almost solely devoted to maintaining the legitimacy of the state and its leading dynasty up to a level where the distinction between nationalism and religion visibly evaporates. The musical establishment is hierarchically organized. At the top are court orchestras, such as the former Unhasu Orchestra, or the currently favoured Moranbong Band, whose style and repertoire is closely controlled by th…
Tradition and Legitimation in North Korea
2017
Since its debut in 2012, the Moranbong Band has served as a key symbol for the Kim Jongun-era ruling style, limited cosmopolitanism, and ultimately political conservatism. This article analyses the legitimacy strategies of North Korean official culture in the light of perceived internal needs for change, even as the foundations of the traditional personality cult remain intact and strengthened by the Band’s performances. Analysis of musical performances online and relevant comparative literature on North Korean music form the core of the article. Finally, the article shows the arc from the Band as an innovative symbol of possible liberalization into a far more conservative implement as time…
Music-related nostalgic experiences of young people living in migration
2012
Music is a powerful means for constructing identity – both formulating and remembering who one is (e.g., DeNora, 2000). A particular situation creating challenges for the sense of self is migration and living in a foreign environment. Therefore, this qualitative study focused on investigating music-related nostalgic experiences in young people living in migration. The aim of the study was to identify features characteristic to music-related nostalgia particularly in relation the experience of migration. Ten university students (aged between 24 – 40 years, 5 males, 5 females) took part in the study. The participants were all Iranian, currently living in migration (in Germany or Finland). Dat…
Two-photon transitions of charmonia on the light front
2022
We investigate the two-photon transitions $H_{c\bar c} \to \gamma^*\gamma$ of the charmonium system in light-front dynamics. The light-front wave functions were obtained from solving the effective Hamiltonian based on light-front holography and one-gluon exchange interaction within the basis light-front quantization approach. We compute the two-photon transition form factors as well as the two-photon decay widths for S- and P-wave charmonia, $\eta_c$ and $\chi_{cJ}$ and their excitations. Without introducing any free parameters, our predictions are in good agreement with the recent experimental measurements by BaBar and Belle, shedding light on the relativistic nature of charmonium.
